Lamar County Multi- Jurisdictional Hazard Mitigation Plan <br />Chapter Three <br />Damage can also be caused by flying debris (referred to as windborne missiles). If wind speeds <br />are high enough, missiles can be thrown at a building with enough force to penetrate widows, <br />walls, or the roof. For example, an object such as a 2" X 4" wood stud weighing 15 pounds, <br />when carried by a 250 -mph wind, can have a horizontal speed of 100 mph and enough force to <br />penetrate most common building materials used in houses today. Even a reinforced masonry <br />wall will bew penetrated unless it has been designed and constructed to resist debris impact <br />during extreme winds. Because missiles can severely damage and even penetrate walls and <br />roofs, they threaten not only buildings but the occupants as well. <br />With thunderstorms also comes lightning. Each second there are 50 to 100 cloud to ground <br />lightning strikes across the U.S. These strikes can kill humans and animals, disrupt utilities, and <br />start wildfires. <br />4. Previous Occurrences <br />Since 2006, the Naitonal Climatic Data Center (NCDC) Recorded 27 thunderstorm and high <br />wind events and 2 reported cases of lightning damage in Lamar County. Due to the rural nature <br />of the County, most reports of thunderstorms and any associated damage are from cities and <br />towns. <br />Table 4a: Thunderstorms 2006 -2011 <br />Location c <br />County <br />Paris <br />003/29/2007 <br />Thunderstorm <br />Wind Speeds <br />(kts) <br />50kts <br />Property <br />Damages (per <br />thousand) <br />15.00K <br />Tigertown <br />04/24/2007 <br />Thunderstorm <br />56 kts <br />5.00K <br />Roxton <br />04/24/2007 <br />Thunderstorm <br />50kts <br />1.00K <br />Paris <br />06/20/2007 <br />Thunderstorm <br />56kts <br />30.00K <br />Novice <br />04/03/2008 <br />Thunderstorm <br />56kts <br />5.00K <br />Paris <br />04/03/2008 <br />Thunderstorm <br />50kts <br />0 <br />Paris <br />04/10/2008 <br />Thunderstorm <br />50 <br />0 <br />Tigertown <br />05/06/2009 <br />Thunderstorm <br />52 <br />2.00 <br />Paris Flying <br />Tiger Airport <br />05/06/2009 <br />Thunderstorm <br />56 <br />125.00 <br />Paris Cox Field <br />05/9/2009 <br />Thunderstorm <br />58 <br />15.00 <br />Paris <br />05/09/2009 <br />Thunderstorm <br />50 <br />0.25 <br />105 <br />
